8 First colour and light­ing

Usu­ally I be­gin with a black and white or monochrome im­age. To start colouris­ing the im­age, I ap­ply a blue colour layer, set to Mul­ti­ply. On a sep­a­rate layer I paint rays of vol­u­met­ric light. It not only helps cre­ate the im­pres­sion of un­der­wa­ter light, but also helps me de­fine which sur­faces should be lit. Di­rec­tional light from above will help me out­line the char­ac­ters.
